| occupational medicine | <study> A branch of medicine concerned with the treatment of patients with occupational and environmental illness and injury. (09 Oct 1997) |
| occupational neurosis | Professional neurosis, a disorder of a group of muscles used chiefly in one's occupation, marked by the occurrence of spasm, paresis, or incoordination on attempt to repeat the habitual movements; e.g., writer's cramp; probably a focal dystonia. Synonym: craft palsy, functional spasm. (05 Mar 2000) |
| occupational safety and health administration | One of the U.S. Agencies responsible for regulation of biotechnology. The major law under which the agency has regulatory powers is the Occupational Safety and Health act. (09 Oct 1997) |

| occupational therapist | <specialist> An individual trained to help people manage the daily activities of living, such as dressing, grooming or cooking, and regaining vocational skills. (05 Mar 2000) |
| occupational therapy | A form of therapy that encourages and instructs manual activities for therapeutic or remedial purposes in mental and physical disorders. (27 Sep 1997) |
| occupational therapy department, hospital | Hospital department responsible for the administration and provision of any occupational or work activity for remedial purposes. (12 Dec 1998) |
| united states occupational safety and health administration | An office in the department of labour responsible for developing and establishing occupational safety and health standards. (12 Dec 1998) |
| magnetically insulated transmission line | <radiobiology> Used to transport power efficiently in vacuum lines at very high power densities. Although the cathode is a space-charge limited electron emitter, the electron flow is confined by self-generated or applied magnetic fields. MITL's are used extensively in light-ion-driven inertial confinement fusion. (09 Oct 1997) |
| vertical transmission | <microbiology> Transmission of a pathogen such as HIV from mother to foetus or baby during pregnancy or birth. See: perinatal transmission. (09 Oct 1997) |
| mass action transmission | <epidemiology> Transmission of infection which occurs at a rate directly proportional to the number or density of both susceptibles and infecteds present. Some authors reserve the name mass action for transmission processes of the form b X Y/N , which we associate with STD-type transmission, and describe transmission rates of the form b X Y , as pseudo-mass action ; the two are equivalent if the population size is unchanging. (05 Dec 1998) |
| perinatal transmission | <microbiology, paediatrics> Transmission of a pathogen, such as HIV, from mother to baby during birth. See: Vertical Transmission. (09 Oct 1997) |
| microscopy, electron, scanning transmission | A type of electron microscopy which scans with an extremely narrow beam that is transmitted through the sample. The detection apparatus produces an image whose brightness depends on the atomic number of the sample. It should not be confused with microscopy, electron scanning nor with microscopy, electron, transmission (see microscopy, electron). (12 Dec 1998) |
| Conventional Transmission Electron Microscopy | <technique> A term applied to 'normal' transmission electron microscopy imaging. The electron beam is passed through a thin film sample (typically ~1-200 nm thick). Bright field diffraction contrast images are formed with the direct (undiffracted) beam. Dark field images are formed with a selected diffracted beam. CTEM imaging is used in the general observation of samples and careful selection of the diffracting conditions of the sample will allow the analysis of defect structures within the sample.
